Question

find the square root of 98 correct to two decimal places ​

Answer 1

Answer:

9.90

Explanation:

If

a,b ≥ 0 then √ab = √a √b

So √98 = √$7^{2}$ ⋅ 2 = √72 √2 =7√2

√98 is irrational, so its decimal representation neither terminates nor repeats.

It can be expressed as a repeating continued fraction.
